Description

  The present invention relates to a background stain preventing composition, and more particularly to a background stain preventing composition that prevents secondary adhesion due to a hair dye by applying to the ear, forehead, etc. before using the hair dye.

As a hair dye that can be easily used in general households, a hair dye composition containing an oxidation dye or a direct dye is known. Such hair dye compositions can be easily dyed in a short time, but when applied to hair, gloves, ear covers, etc. are used to prevent the chemical solution from accidentally adhering to the ears, forehead, hands, etc. Had to be used. Since the skin is composed of protein components like hair, there is a problem that it cannot be easily washed and removed once dyed. Therefore, a background stain preventing agent for preventing secondary adhesion of the dyeing liquid by applying it to the hand / forehead as described in Patent Document 1 has been known. Such a background stain preventing agent is used by blending an oily component and a reducing agent as secondary adhesion preventing components and applying them to a place (ear, forehead, etc.) where the dyeing solution is likely to adhere just before the hair dyeing operation.

Similarly, the oxidative hair dye containing an oxidative dye is apply | coated to the upper arm part in which the background stain | pollution | contamination prevention agent composition is not apply | coated. After 20 minutes, wash each hair dye application site with soap. By comparing the location where each test specimen was applied with the location where the test specimen was not applied, the background stain prevention ability was evaluated according to the following criteria.

Dyeing is not recognized: ○, less dyeing than the part where the test specimen is not applied: Δ, dyed to the same extent as the part where the test specimen is not applied: ×.
<Ease of washing>
Each specimen shown in Table 1 is applied to the upper arm, and after 20 minutes, each specimen location is washed away with tap water. By comparing the location where each specimen was applied with the location where it was not applied, the ease of washing was evaluated according to the following criteria.

No stickiness due to the specimen: ○, little stickiness due to the specimen: Δ, stickiness due to the specimen is strongly felt: x.
<Influence on hair dyeing>
Each test body shown in Table 1 is applied to the head face line with a half head. Do not apply anything to the other as a comparison. Thereafter, an oxidation hair dye was applied, washed off after 30 minutes, and the hair dyeings were compared. The influence on hair dyeing was evaluated according to the following criteria.
